- NASA scientists were surprised to discover a high-speed jet stream near Jupiter's equator.
- The 3,000-mile-wide band of wind is moving at 320 miles per hour, according to NASA.
- Previous telescopes couldn't see Jupiter's atmosphere in such detail so they missed the fierce winds.
NASA's James Webb Space Telescope has helped scientists discover that Jupiter has a thin jetstream whipping around the planet at 320 miles per hour — twice as fast as Earth's strongest hurricanes.
